The first plants that evolved to not require water for transferring sperm to eggs were the gymnosperms, such as conifers and cycads. Gymnosperms produce seeds that are not enclosed in a fruit, allowing them to be dispersed without the need for water for reproduction. This adaptation allowed them to colonize drier environments and diversify during the Paleozoic era.
Gymnosperms developed several key adaptations that allowed them to outcompete spore-bearing plants, primarily the evolution of seeds. Seeds provide a protective coating, a nutrient supply for the developing plant, and the ability to remain dormant until conditions are favorable for germination. Additionally, gymnosperms often have specialized structures like cones for reproduction, which enhance their reproductive efficiency and resilience in various environments. These adaptations contribute to their successful colonization of diverse habitats, surpassing many spore-bearing plants.
The development of a vascular system in plants, which includes xylem and phloem, allowed them to efficiently transport water, nutrients, and sugars throughout their structures. This adaptation supported larger plant sizes by enabling greater structural support and height, facilitating access to sunlight and resources. As a result, vascular plants could dominate terrestrial ecosystems, leading to increased diversity and complexity in plant forms. Overall, the vascular system was crucial for the evolutionary success of larger and more complex plants.
The amniotic egg allowed animals to reproduce on land, leading to the diversification of terrestrial vertebrates. This adaptation provided embryos with protection against desiccation and allowed for the colonization of diverse habitats.
The climate change that allowed flowering plants to increase was the gradual cooling of Earth during the Cretaceous period, which created more temperate climates. This change provided favorable conditions for the diversification and spread of flowering plants, enabling them to outcompete other plant species and dominate terrestrial ecosystems.
The evolution of seeds in gymnosperms allowed them to out-compete spore-bearing plants by providing a protective and nutrient-rich environment for the embryo to develop. Seeds also have adaptations for dispersal, enabling gymnosperms to colonize diverse habitats and spread more efficiently than spores.
The development of seeds allowed plants to spread widely and colonize the land. Seeds could be carried in animals' intestines or blown by the wind to create offspring far from the original plant.
Because it allowed Spain to colonize modern day Peru.

Spores allowed plants to reproduce and disperse in a dry environment, enabling them to colonize land. Spores served as a protective mechanism against desiccation and helped plants survive in diverse habitats. This adaptation was essential for the transition of plants from aquatic to terrestrial environments.
